ITC’S WHEREABOUTS


AFFILIATION

SDIT is a research group on SDI Technology at ITC, University of Twente, The Netherlands.

We partner with governments, NGOs, and private sector worldwide, on technical SDI development.

Partners in: capacity building joint research joint development www.itc.nl/research/themes/sdit/default.asp

SDI – THE REALITY


SDI – SOME PROBLES


An infrastructure that allows the exploitation

of geospatial principles, geospatial functions and geospatial data within and across application and scientific domains, transforming the way in which production,

use, development, research and education are conducted by the

geospatial community

SDI – DEFINED

( Goodchild , et.al., 2010 )


WHAT IS AN SDI FUNDAMENTALLY?

Agreement to collaborate on shared development & exploitation of strategic geoinformation resources

Involves parties in: Government Private sector Academia Public sector

Technical(tools)

Financial(business cases)

Legal(laws)

Organisational(agreements)

SDISDI


SDI TECHNOLOGICALLY DEFINED

A community of actors working in an IT environment

With a special interest in geospatial resources

Wanting to take part in a communication process

With well-understood responsibilities

Involving service offerings & service consumptions

THE SYSTEM TRIPLET FOR SDI

Every SDI node has three characteristics Data and other content Functionality offered through services Ability to engage in communication processes

Content Institutional data

sources App & model results Metadata Sensor data Volunteered data

Services Functions provided as

externally visible services Form the single steps in the

workflow protocols

Communication Mechanisms for successful

participation in workflow protocols

Operations

• GetCapabilities– Returns server-level metadata, description of services and content,

acceptable request parameters

• GetMap– Returns map image whose geospatial and dimensional parameters

are well-defined

• GetFeatureInfo– Returns information about particular features shown on map

IDEGPORTALS


SDI – BEYOND PORTALS

Allow the creation of custom views on available data

Enable the addition of annotations

Create connections to incorporate external data sources and allow those to be shared with others

Provide functionality (well-known GIS functions)

Let users style the data so that it fits their own objectives


SDI – BEYOND PORTALS

Enable data upload (gml, Kml, shp, tiff, ...)

Allow editing, either through a browser or desktop clients using standards (WFS-T)

Implement feedback mechanisms Commenting, tagging, rating

Implement filtering, ranking and other mechanisms to determine fitness for use (most-viewed, most linked to, etc.)

Derive metadata from users actions and use


CONCLUSIONS

What defines success in a SDI in the year 2020, and how to get there?

What do 2015 SDIs achieve?

What should 2030 SDIs achieve?

What is the pathway from 2015 to 2030?

Which are the critical success factors to get there?
